    Phenotypes of a mutant

  • increased sensitivity of sporulating cells to the genotoxic effects of MMS [Pubmed|27698084]

    • The protein

    Catalyzed reaction/ biological activity

  • removes hypoxanthine, 3-alkylated purines, and 1,N6-ethenoadenine from DNA; hypoxanthine and 1,N6-ethenoadenine are the preferred substrates [Pubmed|14729667]
  • protects sporulating cells from cytotoxic and genotoxic effects of MMS [Pubmed|27698084]

    • Protein family

  • DNA glycosylase MPG family (according to Swiss-Prot) AAG family of 3-methyladenine DNA glycosylases
